For those lfs that have stopped bringing in boon. You might try n ask the boss if u can preorder. For eg, if your bettas lay eggs today, ask for boon 4 days later. You might have to order a larger pack. $3 or $5

For ppl in the central area, Wu Hu at Tiong Bahru does bring in boon on pre-order, just ask before hand. It's gonna be $3-5 but it's really a lot. One big pack
